The Dimplex RFI840D31 Wall Insert Large 4000/3000W 240/208V 1PH Almond is a commercial-grade heater designed to warm cold, drafty rooms very quickly. The heater is hardwired into your electrical system and can be either in the ceiling or recessed into your wall. It can be hardwired to produce either 13,648 or 10,236 BTUs and the fan quickly circulates warm air throughout the room, which makes it ideal for drafty areas and rooms with exterior doors, such as hallways, entryways, basements, and workshops.

The Dimplex RFI840D31 Wall Insert Heater uses a nickel chromium heating element encased in a steel sheath with spiral steel fins brazed to the surface. The fins provide faster heat transfer than a traditional open coil setup, common in other heaters of this type. The steel sheath also improves the heater's durability, so it runs longer with fewer problems. The heater comes with a grill made from 20-guage steel and painted with an almond finish made from polyester and epoxy powder coating, which resists fading and abrasion. The fan motor is totally enclosed and permanently lubricated, requiring no additional maintenance.

Thermostat

The Dimplex RFI840D31 Wall Insert Heater controls heat output with a built-in, double-pole thermostat. The thermostat can also be wired into a remote wall stat if desired. Once your temperature has been set, the thermostat will cycle around that temperature, automatically adding more warm air to the room whenever the temperature drops below your set level.

Safety Features

The Dimplex RFI840D31 Wall Insert Heater comes with a protective grill that prevents you from accidentally touching the heating element. To reduce the risk of fires, it also comes with thermal overload protection that deactivates the unit if it starts overheating. The access door can also be locked to prevent anyone from tampering with the unit after it's been installed.
